Is anybody watching the output of their KS-24361? Mine was off by 45 seconds for 13 minutes at the end of Jan 01. I didn't see any problems on a Z3801A.
Receiver time output may have been delayed while receiving an almanac update at the end of the UTC day? Almanac takes about 12.5 minutes to transmit, which would jive with ~13 minutes. Clockstats should output the last message received about once per poll period - is minpoll 6? TFOM byte after time stayed the same at 3 => < 1us uncertainty if same as Z3801A; FFOM two bytes after time went from 0 to 2 so the PLL unlocked and went into holdover, and at the end of that period went to 1 so stabilizing; presumably got back to 0 later. The following Leap, Request for Service, and Valid bytes did not change. Assumptions are that operation and status are the same as for HP Smart Clocks.
Here is part of ntpd's clockstats. The second column is the system time - seconds this day. The 4th column is the data from the KS-24361 The 220160101 is the date. Following that is HHMMSS. The <== mark the first and last samples that are off.
